Abstract
A mixed scrambling operation is defined by the use of Arnold transform and Baker mapping. Following a designed sequence, the combined scrambling operation is utilized for changing the pixel position of secret image under the control of a random matrix. At the same time, the pixel value is altered by random bit shift for obtaining an encrypted image encoded in N-bit data. The operations mentioned above are employed for all pixels of original secret image. Finally an encrypted image is obtained and encoded into N-bit data being from the input image. Some numerical simulations have been achieved for checking the performance of the image hiding scheme.
